FIG. 3A is a plan view illustrating a display apparatus according to anembodiment, and FIG. 3B is a diagram for describing driving of thedisplay apparatus of FIG. 3A.

Referring to FIG. 3A, the display apparatus may include a display panel10. The display panel 10 may include a display area DA and a peripheralarea PA outside the display area DA. The peripheral area PA may be anon-display area in which pixels PX are not arranged. The display areaDA may be completely surrounded by the peripheral area PA. Variouscomponents constituting the display panel 10 are disposed on a substrate100. Accordingly, it may be stated that the substrate 100 includes thedisplay area DA and the peripheral area PA.

A plurality of pixels PX may be arranged in the display area DA. In aplan view, the pixel PX, as used herein, may be defined as an areaconfigured to emit one of red light, green light, blue light, and whitelight in the display area DA.

The pixels PX may include a plurality of first pixels PX1 configured todisplay a first color, a plurality of second pixels PX2 configured todisplay a second color, and a plurality of third pixels PX3 configuredto display a third color. In an embodiment, the first pixel PX1 may be ablue pixel, the second pixel PX2 may be a green pixel, and the thirdpixel PX3 may be a red pixel.

In the present specification, the sizes of the first pixel PX1, thesecond pixel PX2, and the third pixel PX3 may be the sizes of the areasconfigured to emit light, when the display panel 10 is viewed fromabove. For example, the display element implementing each pixel may havean emission area defined by an opening of a pixel defining layer, and atransmission area defined by a first hole H1 and a second hole H2 of alight blocking layer disposed on the display element. In the presentspecification, the size of each pixel means the size of the transmissionarea overlapping the display element implementing each pixel.Accordingly, the width of the transmission area may mean the width ofthe first hole H1 and the width of the second hole H2.

In the display area DA, pixel groups PG in which a certain number ofpixels PX are grouped may be repeatedly arranged in a first directionand a second direction. The pixel groups PG may each include two secondpixels PX2, one first pixel PX1, and one third pixel PX3. The pixelgroups may include a first pixel group PG1 and a second pixel group PG2.In the display area DA, the first pixel group PG1 and the second pixelgroup PG2 may be alternately arranged in a third direction ax1 and afourth direction ax2 crossing the first direction and the seconddirection. In an embodiment, the third direction ax1 may beperpendicular to the fourth direction ax2. In another embodiment, thethird direction ax1 and the fourth direction ax2 may form an acute angleor an obtuse angle with each other. Accordingly, in the display area DA,a first area SDA1 in which the first pixel group PG1 is arranged and asecond area SDA2 in which the second pixel group PG2 is arranged may berepeated in the third direction ax1 and the fourth direction ax2. Thefirst pixel group PG1 and the second pixel group PG2 may have a shape inwhich two second pixels PX2, one first pixel PX1, and one third pixelPX3 are grouped in a rectangle. The first pixel group PG1 and the secondpixel group PG2 are divided into repeating shapes and do not mean astructural disconnection.

When the arrangement structure of the display area DA is expresseddifferently, one of a plurality of first areas SDA1 may be surrounded bya plurality of second areas SDA2. In other words, one of the secondareas SDA2 may be surrounded by the first areas SDA1.

The size (area) of the first area SDA1 may be equal to or different fromthe size (area) of the second area SDA2. FIG. 3A illustrates an examplein which the size (area) of the first area SDA1 is equal to the size(area) of the second area SDA2.

In an embodiment, the arrangement of the first pixel PX1, the secondpixel PX2, and the third pixel PX3 constituting the first pixel groupPG1 may be the same as the arrangement of the first pixel PX1, thesecond pixel PX2, and the third pixel PX3 constituting the second pixelgroup PG2. The size (area) of each of the first pixel PX1, the secondpixel PX2, and the third pixel PX3 in the first pixel group PG1 may begreater than the size (area) of each of the first pixel PX1, the secondpixel PX2, and the third pixel PX3 corresponding thereto in the secondpixel group PG2. That is, the size (area) of the transmission area ofeach of the first pixel PX1, the second pixel PX2, and the third pixelPX3 in the first pixel group PG1 may be greater than the size (area) ofthe transmission area of each of the first pixel PX1, the second pixelPX2, and the third pixel PX3 corresponding thereto in the second pixelgroup PG2. For example, the size (area) of the first hole H1 of thefirst pixel PX1 in the first pixel group PG1 may be greater than thesize (area) of the second hole H2 of the first pixel PX1 in the secondpixel group PG2.

When the viewing angle of each of the first pixel PX1, the second pixelPX2, and the third pixel PX3 in the first pixel group PG1 is 45 degreesor more, luminance may be 30% or more. However, when the viewing angleof each of the first pixel PX1, the second pixel PX2, and the thirdpixel PX3 in the second pixel group PG2 is 45 degrees or more, luminancemay be 10% or less.

The peripheral area PA is an area in which pixels PX are not arranged,and no image is provided. Driving circuits configured to drive thepixels PX, for example, the scan driver 130, the data driver 150, thecontroller 170, and the power supply lines illustrated in FIG. 1 , maybe arranged in the peripheral area PA.

The display apparatus according to an embodiment may operate in a normaldriving mode (a first mode) or a private driving mode (a second mode).The normal driving mode may be a mode that provides a wide viewing anglein all directions. The private driving mode is a mode that provides anarrow viewing angle in at least some directions, and may be a mode inwhich visibility from the side is narrow or blocked, compared with thenormal driving mode. While the display apparatus is operating in theprivate driving mode, the viewing angle of another person, who views thedisplay apparatus from the side, may be narrow or the view may beblocked. Therefore, personal information exposure may be prevented.

When the controller (170 of FIG. 1 ) receives a selection signal forselecting the normal driving mode or the private driving mode, thecontroller may output a control signal to the scan driver (130 of FIG. 1) and the data driver (150 of FIG. 1 ) so that the display apparatusoperates in the normal driving mode or the private driving modeaccording to the selection signal.

In the normal driving mode, all of the first to third pixels PX1, PX2,and PX3 constituting the first pixel group PG1 and the second pixelgroup PG2 of the display area DA may be selected by a scan signal andmay emit light with a luminance corresponding to a corresponding datasignal.

As illustrated in FIG. 3B, in the private driving mode, the first tothird pixels PX1, PX2, and PX3 constituting the first pixel group PG1 ofthe display area DA do not emit light, and only the first to thirdpixels PX1, PX2, and PX3 constituting the second pixel group PG2 mayemit light with a luminance corresponding to a corresponding datasignal. The non-emission of the pixels may include a case in which thepixel is not selected by a scan signal and thus does not receive a datasignal, or a case in which the pixel is selected by the scan signal, butreceives a black data signal and expresses black.

The first conductive line ML1 may be disposed to overlap the pixeldefining layer 209 in the thickness direction (z-direction), asillustrated in FIG. 8 . For example, the first conductive line ML1 maybe disposed to overlap the pixel defining layer 209 surrounding the(1-1)th emission area EA1 a and the (1-2)th emission area EA1 b.

The anti-reflection layer 600 may be disposed on the input sensing layer400. The anti-reflection layer 600 may include a color filter layer 600a and an overcoat layer 600 b.

The color filter layer 600 a may include a (1-1)th color filter CF1 aand a (1-2)th color filter CF1 b. The (1-1)th color filter CF1 a mayhave a color corresponding to light emitted from the (1-1)th emissionarea EA1 a, and the (1-2)th color filter CF1 b may have a colorcorresponding to light emitted from the (1-2)th emission area EA1 b. Inan embodiment, when blue light is emitted from the (1-1)th emission areaEA1 a, the (1-1)th color filter CF1 a may be a blue color filter, andwhen green light is emitted from the (1-2)th emission area EA1 b, the(1-2)th color filter CF1 b may be a green color filter. Because thecolor filter layer 600 a improves the light extraction efficiency oflight extracted to the front of the display panel 10, the lifespan ofthe display apparatus may be secured even when the light blocking layer710 is provided, so as to block visibility from the side.

The (1-1)th color filter CF1 a may cover the (1-1)th emission area EA1a, and the (1-2)th color filter CF1 b may cover the (1-2)th emissionarea EA1 b. In an embodiment, in a plan view, an edge of the (1-1)thcolor filter CF1 a may be located outside of the (1-1)th opening OP1 a,and an edge of the (1-2)th color filter CF1 b may be located outside ofthe (1-2)th opening OP1 b. The (1-1)th color filter CF1 a and the(1-2)th color filter CF1 b, which are arranged adjacent to each other,may overlap a portion of the pixel defining layer 209 disposed betweenthe (1-1)th opening OP1 a and the (1-2)th opening OP1 b. In anembodiment, the (1-1)th color filter CF1 a and the (1-2)th color filterCF1 b may overlap each other on the first conductive line ML1 in thethickness direction. Accordingly, the first conductive line ML1 may becovered with one or more color filters CF1 a and CF1 b having differentcolors from each other. Because the (1-1)th color filter CF1 a and the(1-2)th color filter CF1 b overlap each other on the first conductiveline ML1, the reflectance of light (external light) incident from theoutside toward the display panel 10 due to the first conductive line ML1may be reduced. In this case, the (1-1)th color filter CF1 a and the(1-2)th color filter CF1 b may be covered with a portion of the lightblocking layer 710 disposed between the (1-1)th emission area EA1 a andthe (1-2)th emission area EA1 b.

The overcoat layer 600 b may include a colorless light-transmittingmaterial, such as an acrylic resin, and may planarize the unevenness ofthe upper surface of the color filter layer 600 a, which is due to theoverlapping between the (1-1)th color filter CF1 a and the (1-2)th colorfilter CF1 b. Also, the thickness of the overcoat layer 600 b may beadjusted to control the distance between the (1-1)th and (1-2)themission areas EA1 a and EA1 b and the light blocking layer 710.

The optical function layer 700 may be disposed on the anti-reflectionlayer 600. The optical function layer 700 may include the light blockinglayer 710 and a planarization layer 730 for planarizing the uppersurface of the light blocking layer 710.

As described above, the light blocking layer 710 may at least partiallyabsorb external light or internally reflected light. The light blockinglayer 710 may include a black pigment. The light blocking layer 710 mayinclude a black matrix. The first holes H1 through which light emittedfrom the first organic light-emitting diode OLED1 is transmitted isdefined in the light blocking layer 710. For example, A (1-1)th hole H1a defining a (1-1)th transmission area HA1 a and a (1-2)th hole H1 bdefining a (1-2)th transmission area HA1 b is formed in the lightblocking layer 710. The (1-1)th transmission area HA1 a may overlap the(1-1)th light emission area EA1 a, and the (1-2)th transmission area HA1b may overlap the (1-2)th emission area EA1 b in the thicknessdirection.

In an embodiment, in a plan view, the (1-1)th opening OP1 a may belocated in the (1-1)th hole H1 a. Similarly, in a plan view, the (1-2)thopening OP1 b may be located in the (1-2)th hole H1 b. For example, oneedge of the (1-1)th opening OP1 a may be apart from the one edge of the(1-1)th hole H1 a by a first distance d1.

In an embodiment, a width w1 of a portion of the pixel defining layer209 disposed between the (1-1)th emission area EA1 a and the (1-2)themission area EA1 b may be greater than a width w3 of a portion of thelight blocking layer 710 disposed between the (1-1)th transmission areaHA1 a and the (1-2)th transmission area HA1 b. Therefore, the (1-1)themission area EA1 a may be exposed through the (1-1)th hole H1 a, andthe (1-2)th emission area EA1 b may be exposed through the (1-2)th holeH1 b.

In an embodiment, a width w2 of the first conductive line ML1overlapping a portion of the pixel defining layer 209 disposed betweenthe (1-1)th emission area EA1 a and the (1-2)th emission area EA1 b maybe less than the width w3 of a portion of the light blocking layer 710disposed between the (1-1)th transmission area HA1 a and the (1-2)thtransmission area HA1 b. Therefore, in a plan view, the first conductiveline ML1 may be covered with the light blocking layer 710.

Referring to FIG. 10 , the second organic light-emitting diode OLED2arranged in the second area SDA2 may include a (2-1)th organiclight-emitting diode OLED2 a and a (2-2)th organic light-emitting diodeOLED2 b.

Therefore, the (2-1)themission area EA2 a may be exposed through the (2-1)th hole H2 a, andthe (2-2)th emission area EA2 b may be exposed through the (2-2)th holeH2 b. In an embodiment, a width w3 of a portion of the light blockinglayer 710 disposed between the (1-1)th transmission area HA1 a and the(1-2)th transmission area HA1 b may be less than the width w4 of aportion of the light blocking layer 710 disposed between the (2-1)thtransmission area HA2 a and the (2-2)th transmission area HA2 b.

FIGS. 11A and 11B are diagrams for describing the planar shapes ofpixels arranged in a first area SDA1 and a second area SDA2. FIGS. 11Aand 11B are similar to FIGS. 7A and 7B, but differ from FIGS. 7A and 7Bin that a pixel defining layer 209 has first sub-openings SOP1 andsecond sub-openings SOP2 dividing one emission into a plurality ofsub-emission areas, and a light blocking layer 710 has first sub-holesSH1 overlapping the first sub-openings SOP1 and second sub-holes SH2overlapping the second sub-openings SOP2. Hereinafter, descriptions ofsimilar or redundant components will be omitted, and differences will bemainly described.

Referring to FIGS. 11A and 11B, the pixel defining layer 209 may bearranged in the first area SDA1 and the second area SDA2. The pixeldefining layer 209 may have the first sub-openings SOP1 exposing aportion of a pixel electrode of a first organic light-emitting diodeOLED1. For example, the first sub-openings SOP1 may be defined bydividing an emission area corresponding to one pixel electrode of thefirst organic light-emitting diode OLED1 into a plurality ofsub-emission areas. The pixel defining layer 209 may have the secondsub-openings SOP2 exposing a portion of a pixel electrode of a secondorganic light-emitting diode OLED2. For example, the second sub-openingsSOP2 may be defined by dividing an emission area corresponding to onepixel electrode of the second organic light-emitting diode OLED2 into aplurality of sub-emission areas. In a plan view, the first sub-openingSOP1 and the second sub-opening SOP2 may each have a circular shape, anelliptical shape, or a polygonal shape. The polygon may include asquare, a rectangle, and a rhombus, and may have a rounded corner shape.In this regard, FIG. 11A illustrates the first sub-opening SOP1 and thesecond sub-opening SOP2 each having a rectangular shape, and FIG. 11Billustrates the first sub-opening SOP1 and the second sub-opening SOP2each having a rectangular shape with rounded corners. In an embodiment,one of the first sub-opening SOP1 and the second sub-opening SOP2 mayhave a rectangular shape, and the other of the first sub-opening SOP1and the second sub-opening SOP2 may have a rectangular shape withrounded corners.

The size (area) of each of the first sub-openings SOP1 dividing theemission area of the first organic light-emitting diode OLED1 may beequal to or greater than the size (area) of each of the secondsub-openings SOP2 dividing the emission area of the second organiclight-emitting diode OLED2 that emits the same color as that of thefirst organic light-emitting diode OLED1. Hereinafter, a case in whichthe size (area) of the first sub-opening SOP1 is equal to the size(area) of the second sub-opening SOP2, as illustrated in FIG. 11 , willbe mainly described in detail.

First sub-holes SH1 overlapping the first sub-openings SOP1 and secondsub-holes SH2 overlapping the second sub-openings SOP2 are defined inthe light blocking layer 710. For example, the light blocking layer 710may have a first partition PT1 dividing the first hole H1 illustrated inFIG. 7 into a plurality of first sub-holes SH1 and a second partitionPT2 dividing the second hole H2 illustrated in FIG. 7 into a pluralityof second sub-holes SH2. In an embodiment, the light blocking layer 710may have only the second partition PT2 dividing the second hole H2 intothe second sub-holes SH2. In a plan view, the first sub-hole SH1 and thesecond sub-hole SH2 may each have a circular shape, an elliptical shape,or a polygonal shape. The polygon may include a square, a rectangle, anda rhombus, and may have a rounded corner shape. In this regard, FIG. 11Aillustrates the first sub-hole SH1 and the second sub-hole SH2 eachhaving a rectangular shape, and FIG. 11B illustrates the first sub-holeSH1 and the second sub-hole SH2 each having a rectangular shape withrounded corners. In an embodiment, one of the first sub-hole SH1 and thesecond sub-hole SH2 may have a rectangular shape, and the other of thefirst sub-hole SH1 and the second sub-hole SH2 may have a rectangularshape with rounded corners.

The size (area) of each of the first sub-holes SH1 overlapping theemission area of the first organic light-emitting diode OLED1 may bedifferent from the size (area) of each of the second sub-holes SH2overlapping the emission area of the second organic light-emitting diodeOLED2 that emits light of the same color as that of the first organiclight-emitting diode OLED1. In an embodiment, the size (area) of thefirst sub-hole SH1 may be greater than the size (area) of the secondsub-hole SH2.

In a plan view, the first sub-opening SOP1 of the pixel defining layer209 may be located in the first sub-hole SH1 of the light blocking layer710 overlapping the first sub-opening SOP1. Similarly, the secondsub-opening SOP2 of the pixel defining layer 209 may be located in thesecond hole SH2 of the light blocking layer 710 overlapping the secondsub-opening SOP2. In an embodiment, a distance from one edge of thefirst sub-opening SOP1 to one edge of the first sub-hole SH1 may begreater than a distance from one edge of the second sub-opening SOP2 toone edge of the second sub-hole SH2. Therefore, a viewing angle of thefirst organic light-emitting diode OLED1 may be greater than a viewingangle of the second organic light-emitting diode OLED2.

In order to describe the arrangement of pixels arranged in a first areaSDA1 and a second area SDA2 and the arrangement of a conductive meshpattern and a dummy pattern of an input sensing layer 400, FIG. 12illustrates a first organic light-emitting diode OLED1, a second organiclight-emitting diode OLED2, a pixel defining layer 209, a light blockinglayer 710, and a first conductive line ML1 and a dummy pattern 430 ofthe input sensing layer 400, and other components are omitted forconvenience of illustration. Although FIG. 12 illustrates the firstconductive line ML1 as the conductive mesh pattern of the input sensinglayer 400, the conductive mesh pattern may be the second conductive lineML2 according to a location thereof.

Referring to FIG. 12 , the first conductive line ML1 may have aconductive mesh pattern and may include a mesh hole. In an embodiment,the first conductive line ML1 may be disposed to cross over the firstarea SDA1 to have a plurality of mesh holes. In a plan view, firstsub-openings SOP1 of the pixel defining layer 209 may be arranged in themesh holes. Similarly, the first conductive line ML1 may be disposed tocross over the second area SDA2 to have a plurality of mesh holes. In aplan view, the second sub-openings SOP2 of the pixel defining layer 209may be arranged in the mesh holes.

The dummy pattern 430 may be arranged to surround at least a portion ofthe first sub-openings SOP1 and the second sub-openings SOP2. Forexample, the dummy pattern 430 may be disposed to overlap a portion ofthe pixel defining layer 209 between the first sub-openings SOP1adjacent to each other and a portion of the pixel defining layer 209between the second sub-openings SOP2 adjacent to each other.

In an embodiment, the dummy pattern 430 may be provided in the firstconductive layer (CML1 of FIG. 6 ). In another embodiment, the dummypattern 430 may be provided in the second conductive layer (CML2 of FIG.6 ). In another embodiment, a portion of the dummy pattern 430 may beprovided in the first conductive layer CML1, and another portion of thedummy pattern 430 may be provided in the second conductive layer CML2.The dummy pattern 430 may be insulated from the first conductive lineML1 and the second conductive line (ML2 of FIG. 6 ). For example, thedummy pattern 430 may be arranged spaced apart from the conductive meshpattern in the mesh hole.

The light blocking layer 710 may be disposed on the first conductiveline ML1, and may cover the first conductive line ML1 and the dummypattern 430 in a plan view. That is, in a plan view, the firstconductive line ML1 and the dummy pattern 430 may overlap the lightblocking layer 710, and the first sub-hole SH1 and the second sub-holeSH2 of the light blocking layer 710 may be at least partially surroundedby the first conductive line ML1 and the dummy pattern 430,respectively. For example, in a plan view, the first partition PT1 andthe second partition PT2 of the light blocking layer 710 may cover thedummy pattern 430. Therefore, the light blocking layer 710 may reducethe reflection of light (external light) incident from the outsidetoward the display panel 10 due to the first conductive line ML1 and thedummy pattern 430.

Referring to FIG. 13 , (1-1)th sub-openings SOP1 a exposing portions ofa pixel electrode 210 a of a (1-1)th organic light-emitting diode OLED1a and (1-2)th sub-openings SOP1 b exposing portions of a pixel electrode210 b of a (1-2)th organic light-emitting diode OLED1 b are defined inthe pixel defining layer 209.

The input sensing layer 400 may include a dummy pattern 430. In anembodiment, the dummy pattern 430 may be arranged on the same layer as afirst conductive line ML1. The dummy pattern 430 overlaps the pixeldefining layer 209 in the thickness direction (z-direction). Forexample, the dummy pattern 430 may be disposed between a second touchinsulating layer 403 and a third touch insulating layer 405. In anotherembodiment, the dummy pattern 430 may be disposed between a first touchinsulating layer 401 and a second touch insulating layer 403.

The light blocking layer 710 may have (1-1)th sub-holes SH1 a throughwhich light emitted from the (1-1)th organic light-emitting diode OLED1a is transmitted and (1-2)th sub-holes SH1 b through which light emittedfrom the (1-2)th organic light-emitting diode OLED1 b is transmitted.For example, the (1-1)th sub-holes SH1 a may define (1-1)thsub-transmission areas SHA1 a, and the (1-2)th sub-holes SH1 b maydefine (1-2)th sub-transmission areas SHA1 b. The (1-1)thsub-transmission area SHA1 a may overlap the (1-1)th sub-emission areaSEA1 a, and the (1-2)th sub-transmission area SHA1 b may overlap the(1-2)th sub-emission area SEA1 b.

In an embodiment, in a plan view, the (1-1)th sub-opening SOP1 a may belocated in the (1-1)th sub-hole SH1 a. For example, an edge of the(1-1)th sub-opening SOP1 a may be spaced apart from the an edge of the(1-1)th sub-hole SH1 a by a third distance d3. Similarly, the (1-2)thsub-opening SOP1 b may be located in the (1-2)th sub-hole SH1 b.

In an embodiment, a width w5 of the portion 209P of the pixel defininglayer 209 disposed between the (1-1)th sub-emission areas SEA1 aadjacent to each other may be greater than a width w7 of a firstpartition PT1 disposed between the (1-1)th sub-transmission areas SHA1a. Therefore, the (1-1)th sub-emission areas SEA1 a may be exposedthrough the (1-1)th sub-holes SH1 a. Similarly, the (1-2)th sub-emissionareas SEA1 b may be exposed through the (1-2)th sub-holes SH1 b.

In an embodiment, a width w6 of the dummy pattern 430 overlapping theportion 209P of the pixel defining layer 209 disposed between the(1-1)th sub-emission areas SEA1 a adjacent to each other may be lessthan the width w7 of the first partition PT1 between the (1-1)thsub-transmission areas SHA1 a. Therefore, in a plan view, the entiredummy pattern 430 may be covered with the light blocking layer 710.

Referring to FIG. 14 , (2-1)th sub-openings SOP2 a and (2-2)thsub-openings SOP2 b are defined in a pixel defining layer 209. The(2-1)th sub-openings SOP2 a may expose portions of a pixel electrode 210a of a (2-1)th organic light-emitting diode OLED2 a. Similarly, the(2-2)th sub-opening SOP2 b may expose portions of a pixel electrode 210b of a (2-2)th organic light-emitting diode OLED2 b. The (2-1)thsub-openings SOP2 a may define sub-emission areas SEA2 a of the (2-1)thorganic light-emitting diode OLED2 a, and the (2-2)th sub-openings SOP2b may define sub-emission areas SEA2 b of the (2-2)th organiclight-emitting diode OLED2 b.

A dummy pattern 430 may be disposed to overlap a portion 209P of thepixel defining layer 209 disposed between two adjacent (2-1)thsub-openings SOP2 a.

A light blocking layer 710 may have (2-1)th sub-holes SH2 a throughwhich light emitted from the (2-1)th organic light-emitting diode OLED2a is transmitted, and (2-2)th sub-holes SH2 b through which lightemitted from the (2-2)th organic light-emitting diode OLED2 b istransmitted. For example, the (2-1)th sub-holes SH2 a may define (2-1)thsub-transmission areas SHA2 a, and the (2-2)th sub-holes SH2 b maydefine (2-2)th sub-transmission areas SHA2 b. The (2-1)thsub-transmission area SHA2 a may overlap the (2-1)th sub-emission areaSEA2 a, and the (2-2)th sub-transmission area SHA2 b may overlap the(2-2)th sub-emission area SEA2 b.

In an embodiment, in a plan view, the (2-1)th sub-opening SOP2 a may belocated in the (2-1)th sub-hole SH2 a. For example, an edge of the(2-1)th sub-opening SOP2 a may be spaced apart from the an edge of the(2-1)th sub-hole SH2 a by a fourth distance d4. Similarly, the (2-2)thsub-opening SOP2 b may be located in the (2-2)th sub-hole SH2 b.

In an embodiment, a width w5 of the portion 209P of the pixel defininglayer 209 between the (2-1)th sub-emission areas SEA2 a adjacent to eachother may be greater than a width w9 of a second partition PT2 betweenthe (2-1)th sub-transmission areas SHA2 a. Therefore, the (2-1)thsub-emission areas SEA2 a may be exposed through the (2-1)th sub-holesSH2 a. Similarly, the (2-2)th sub-emission areas SEA2 b may be exposedthrough the (2-2)th sub-holes SH2 b.

In an embodiment, a width w8 of the dummy pattern 430 overlapping theportion 209P of the pixel defining layer 209 disposed between the(2-1)th sub-emission areas SEA2 a adjacent to each other may be lessthan the width w9 of the second partition PT2 between the (2-1)thsub-transmission areas SHA2 a. Therefore, in a plan view, the entiredummy pattern 430 may be covered with the light blocking layer 710.

A fourth distance d4 from one edge of the (2-1)th sub-opening SOP2 a toone edge of the (2-1)th sub-hole SH2 a may be less than the thirddistance d3 illustrated in FIG. 13 . Therefore, light traveling from the(2-1)th organic light-emitting diode OLED2 a in a direction crossing thethickness direction (z-direction) perpendicular to the upper surface ofthe substrate 100 may be further removed than light traveling from the(1-1)th organic light-emitting diode OLED1 a in a direction crossing thethickness (z-direction) perpendicular to the upper surface of thesubstrate 100. For example, the luminance when the viewing angle in thefirst area DA1 is 45 degrees or more may be 30% or more of the luminancewhen viewed from the front of the display panel 10, and the luminancewhen the viewing angle in the second area DA2 is 45 degrees or more maybe 10% or less of the luminance when viewed from the front of thedisplay panel 10. That is, the display panel 10 may provide a narrowerviewing angle in the second area DA2 than in the first area DA1.

FIG. 15 is a diagram for describing the function of the dummy pattern430 according to an embodiment.

Referring to FIG. 15 , the dummy pattern 430 may be disposed to overlapthe portion 209P of the pixel defining layer 209 between sub-emissionareas SEA and SEA′ adjacent to each other. In an embodiment, the dummypattern 430 may be included in the second conductive layer CML2 of theinput sensing layer 400. In another embodiment, the dummy pattern 430may be included in the first conductive layer (CML1 of FIG. 6 ) of theinput sensing layer 400.

The dummy pattern 430 may include the same material as that of the firstconductive line ML1. For example, the dummy pattern 430 may includemolybdenum (Mo), mendelevium (Mb), silver (Ag), titanium (Ti), copper(Cu), aluminum (Al), and/or any alloy thereof.

The dummy pattern 430 may function as a light blocking layer. Forexample, when there is no dummy pattern 430, light emitted from onesub-emission area SEA may not be emitted to the overlappingsub-transmission area SHA, but may be emitted through the adjacentsub-transmission area SHA′. The dummy pattern 430 blocks the path oflight emitted through the adjacent sub-transmission area SHA′.Therefore, when viewed from the side, the display apparatus may bedesigned to minimize or block the viewing angle.

FIGS. 16 and 17 are plan views schematically illustrating a portion of adisplay apparatus, according to an embodiment. FIGS. 16 and 17illustrate the planar shapes of pixels arranged in a first area SDA1 anda second area SDA2 according to embodiments.

Referring to FIG. 16 , a pixel defining layer 209 may be arranged in thefirst area SDA1 and the second area SDA2. First sub-openings SOP1exposing a portion of a pixel electrode of a first organiclight-emitting diode OLED1 and second sub-openings SOP2 exposing aportion of a pixel electrode of a second organic light-emitting diodeOLED2 are defined in the pixel defining layer 209.

In an embodiment, the first sub-openings SOP1 may expose a portion ofthe pixel electrode of the first organic light-emitting diode OLED1. Inan embodiment, the first sub-opening SOP1 may divide one pixel electrodeinto one or more sub-emission areas. Similarly, the second sub-openingsSOP2 may expose a portion of the pixel electrode of the second organiclight-emitting diode OLED2. In an embodiment, the second sub-openingSOP2 may divide one pixel electrode into one or more sub-emission areas.

In a plan view, the first sub-opening SOP1 and the second sub-openingSOP2 may have a circular shape or an elliptical shape.

A light blocking layer 710 that at least partially absorbs externallight or internally reflected light may be disposed on the pixeldefining layer 209. A first sub-hole SH1 overlapping the firstsub-opening SOP1 and a second sub-hole SH2 overlapping the secondsub-opening SOP2 are defined in the light blocking layer 710. In a planview, the first sub-hole SH1 may have a shape similar to that of thefirst sub-opening SOP1, and the second sub-hole SH2 may have a shapesimilar to that of the second sub-opening SOP2.

A distance from an edge of the first sub-opening SOP1 to an edge of thefirst sub-hole SH1 may be greater than a distance from an edge of thesecond sub-opening SOP2 to an edge of the second sub-hole SH2.Therefore, a viewing angle of the first organic light-emitting diodeOLED1 may be greater than a viewing angle of the second organiclight-emitting diode OLED2.

Although not illustrated in FIG. 16 , the first conductive layer (CML1of FIG. 6 ) or the second conductive layer (CML2 of FIG. 6 ) may includea dummy pattern (not illustrated) surrounding at least a portion of thesecond sub-openings SOP2. In an embodiment, the first conductive layer(CML1 of FIG. 6 ) or the second conductive layer (CML2 of FIG. 6 ) mayfurther include a dummy pattern (not illustrated) surrounding at least aportion of the first sub-openings SOP1.

As illustrated in FIG. 16 , because the first sub-opening SOP1, thesecond sub-opening SOP2, the first sub-hole SH1, and the second sub-holeSH2 have a circular shape, a color shift according to an azimuth anglemay be reduced.

Referring to FIG. 17 , a pixel defining layer 209 may be arranged in afirst area SDA1 and a second area SDA2. The pixel defining layer 209 mayhave first openings OP1 exposing a portion of a pixel electrode of afirst organic light-emitting diode OLED1, and second sub-openings SOP2exposing a portion of a pixel electrode of a second organiclight-emitting diode OLED2.

For example, the pixel electrode of the first organic light-emittingdiode OLED1 arranged in the first area SDA1 may be exposed through onefirst opening OP1. On the other hand, the pixel electrode of the secondorganic light-emitting diode OLED2 arranged in the second area SDA2 maybe divided into one or more sub-emission areas by the secondsub-openings SOP2.

In a plan view, the first opening OP1 and the second sub-opening SOP2may have a circular shape, an elliptical shape, or a polygonal shape.The polygon may include a square, a rectangle, and a rhombus, and mayhave a round corner shape. In this regard, FIG. 17 illustrates the firstopenings OP1 and the second sub-openings SOP2 each having a rectangularshape. In an embodiment, the first opening OP1 and the secondsub-opening SOP2 may each have a rectangular shape with rounded corners.One of the first opening OP1 and the second sub-opening SOP2 may have arectangular shape, and the other of the first opening OP1 and the secondsub-opening SOP2 may have a rectangular shape with rounded corners.

A light blocking layer 710 that at least partially absorbs externallight or internally reflected light may be disposed on the pixeldefining layer 209. The light blocking layer 710 has a first hole H1overlapping the first opening OP1 and a second sub-hole SH2 overlappingthe second sub-opening SOP2. In a plan view, the first hole H1 may havea shape similar to that of the first opening OP1, and the secondsub-hole SH2 may have a shape similar to that of the second sub-openingSOP2.

Although not illustrated in FIG. 17 , the first conductive layer (seeCML1 of FIG. 6 ) or the second conductive layer (see CML2 of FIG. 6 )may include a dummy pattern (not illustrated) surrounding at least aportion of the second sub-openings SOP2.

A distance from an edge of the first opening OP1 to an edge of the firsthole H1 may be greater than a distance from an edge of the secondsub-opening SOP2 to an edge of the second sub-hole SH2. Therefore, aviewing angle of the first organic light-emitting diode OLED1 may begreater than a viewing angle of the second organic light-emitting diodeOLED2. Because the opening area of the first organic light-emittingdiode OLED1 increases, the lifespan of the display apparatus may beimproved.

According to embodiments, because the display apparatus includes thelight blocking layer and the anti-reflection layer including the colorfilter, the display apparatus may improve light extraction efficiency oflight extracted to the front of the display apparatus and minimize orblock visibility from the side. Therefore, it is possible to preventinformation displayed on the display apparatus from being exposed topeople around the user.

According to embodiments, the display apparatus capable of minimizingthe risk of personal information exposure in public facilities andmulti-use facilities may be provided. However, such an effect is anexample.
